Kitty-Cat--An Easy-to-Build Catamaran (Pub. No. 5237)

by John Long

Whether you’re looking for something really different or just want a light, fast-sailing boat that’s easy to build and can take a lot of punishment, you’ll want to own "Kitty-Cat". This handsome little catamaran is guaranteed to inspire comments of envy and admiration wherever she makes an appearance, and she leaves mighty little to be desired in the way of snappy performance. The sailing catamaran had its origin in the South Seas. Hundreds of years ago, the islanders astounded the first white visitors with the speed and agility of their unusual craft. Early New England whalers are generally credited with bringing first reports on the fast little twin—hulled native boats to this country. During the past century, many “cats” have been built in all parts of the world. The type has continued to fluorish in Polynesia; today, Hawaii is the acknowledged center of catamaran activity, and the cats are currently enjoying steadily increasing popularity in the United States.

Pollywog (Pub. No. 5242)

by William Garden, Naval Architect

"Pollywog" was designed for young people who love cruising. Lively under sail and roomy on deck and below, she’s a good type to acquire when thoughts of a voyage of exploration begin pushing aside studies and other trifles. While she is but 18 feet long (the size of the usual day-sailer), she has adequate depth and enough outside ballast to enable her to make coastwise passages in safety—and for exploring, the draft of less than three feet is ideal. For auxiliary power, we suggest installing a one-cylinder, four or five-hp marine engine. The layout in the snug cuddy cabin has been kept simple to allow maximum use of the available room. A piece of netting runs along each side for stowing clothes and gear. A couple of air mattresses on the flooring are ideal for sleeping or lounging. Two shelves at the forward end of the cabin take cooking utensils and food. The cockpit is long enough so that it can be converted into an extra sleeping location by rigging a tent oyer the boom.

Discovery (Pub. No. 5249)

by William Garden, Naval Architect

"Discovery" is a little ship with big possibilities. She needs but a small cash outlay, she’s simple in construction, and she’s one of the most useful boats per dollar that it is possible to devise. On an overall length of 22 feet, she can be built complete with outboard for under $750--and built by anyone with the tools and know-how to knock together a flat~pttomed skiff. When completed, she looks shapely, sails beautifully, and runs along at five knots with a 2-hp outboard. If desired, she can be driven by any inboard engine with a displacement of less than 60 cu. in. She’s grand for either cruising or say-sailing. Her form is exactly like that of a big skiff with keel, deck, and rig added. Construction follows the same methods.

Iceboat Scoot, The (Pub. No. 5252)

The unique arrangement of the sail and rigging plan of "Scoot" will be apparent as soon as you begin construction of the parts. This special rigging is the secret of the extraordinary sailing qualities that make "Scoot" a top-flight performer

Featuring rudderless steering and a flat, shell-type hull, here’s a unique 15-ft. racing iceboat, the original of which dates back historically to early days when it was used in lifesaving work on New Jersey’s Great South Bay. Born of the necessity of being able to cross the bay even when it was only partly frozen, "Scoot", in addition to its high speed and extraordinary maneuverability, is noted for its ability to take to open water, if necessary, in hurdling large patches of broken ice. Speeds greater than 80 m.p.h., achieved with as many as four passengers, put "Scoot" in the racing class. As a result of its fourpoint runner suspension, its maneuverability is extremely flexible, permitting sharp turns without danger of capsizing or skidding. Steered by manipulating a large-size jib sail, "Scoot" can be held on an arrowstraight course or turned almost literally on a dime. As designed and built by Bill Harless, noted racing champion, this version of the scooter-type iceboat is the result of prolonged experimentation and development. The hook sail rig used is, in effect, a highperformance airfoil and, because of it, Scoot glides along effortlessly in the mildest breezes and really scoots past competition with a strong wind. The boat is moored by merely tipping it on edge with the sails flat on the ice. Except where modified to simplify construction, the plans presented here were taken directly from the actual boat. Original hardware, which was especially designed and cast in brass, has been replaced with less expensive fittings that can readily be improvised from common parts easily obtainable.

Gulfweed (Pub. No. 5263)

by John G. Hanna

In 1900 Capt. Thomas Fleming Day (then editor of the Rudder) with the collaboration of Larry Huntington and C. D. Mower, got out plans for a 25-foot skipjack arranged as a shoal draft cruiser. In 1901 Capt. Day had a boat built from these plans, named "Sea Bird". In the next ten years he sailed her thousands of miles coastwise, adding a keel in place of the original centerboard, and later a 3 H.P. Knox engine, and in 1911 he sailed her across the Atlantic. The wonderful abilities of the model were thus brought to the attention of boat lovers everywhere. I feel certain that the true skipjack form is the best that can be devised for a small sailing craft, and so I have, followed it faithfully. It has the additional merit that it requires less twist in the planking than most V-bottom hulls, and a sharply twisted plank is a harder building job than a steam bent frame. As compared with "Sea Bird", "Gulfweed" has a little deeper V-bottom, a little more flare in the topsides, higher freeboard, and a bow and stern like those of the skipjacks I am familiar with on the Gulf of Mexico, instead of the sharply turned—up plumb stem and long stern overhang of "Sea Bird". Anyone building "Gulfweed" may be certain of getting a boat of thoroughly proven merit, a long established model of known capability--not an experiment.

Blue Bird is a Sailer (Pub. No. 5269)

by William D. Jackson, Naval Architect

Here is a small fast-traveling dinghy that can be equipped with oars, sails or motor

Most small dinghys do not sail well but this 10-ft. long "Blue Bird" is fast and points fairly high. It makes an excellent utility boat, and, if sailing equipment is not available, you can use the boat with a pair of 6½ ft. oars or with a long shaft Evinrude outboard motor of not over 3 hp. (If you use a standard shaft length outboard motor, you’ll have to cut the transom down, and injure the boat’s performance.) The difficult joinery work of construction is eliminated, but you should try hard to produce close accurate joints. Use mahogany, birch or maple plywood of exterior type, formerly called waterproof. Fir plywood can be used if it,is treated with first coater such as U.S. Plywood’s Firzite, and then painted or varnished.

Sea Explorer--A 27 Ft. Camp Ketch (Pub. No. 5277)

by William Garden, N.A.

This little ketch was designed originally for the Portland Sea Explorer Association in response to the need for an all-around boat to replace the whaleboats and other miscellaneous types. The old boats had turned in years of good service, but in view of repair costs and difficulties in racing as a class, they were a losing proposition for low budgets, plus a widening realization by the Association of the training value in class racing. Several possibilities were examined and the final result was dictated by requirements for light weight and the use of marine plywood. In studying the plans it will become apparent that this is a specialized boat suitable for beaching to unload a crew of boys and their gear as well as affording performance under sail or oars. Eight or ten boys could have a wonderful two weeks cruising with such a boat along an interesting coast line. You will note that there is no provision for a motor, but it has three pair of oarlocks. In calm weather she can be rowed at a fair speed to make an anchorage and the crew can sleep on board or come ashore. Under sail she will be an excellent performer with the lead shoe plus live ballast. Eight boys to windward will provide stability in a real breeze and the rig can be shortened down readily by pulling the mizzen or tucking a reef in the main. Two headsails are shown; in light weather the 270 Genoa Jib will give a lot of power to keep her competitive and a spinnaker may be fitted. The basic reasoning behind the shoal draft was to make the boat portable with the ability to be trucked into other areas for exploring and for regattas. As she is designed, the concept fits in with a summer came use and other specialized service.

Sail Skimr--A 14 Ft Sailboard/Day Sailer (Pub. No. 5279)

by Donald H. Smith, N.A.

Well designed and easy to build; here is fun sailing at its best! This 14-ft. hull is surprisingly easy to plank since there are no twists anywhere.

Thre is a gap between what is generally called a sailboard and a full-fledged sail boat. "Sail Skimr" has been designed to bridge this gap and provide an easy-to-build, low-cost craft. Her 50” beam is generous for a boat of this type and there is plenty of freeboard which goes far in lifting "Sail Skimr" out of the sailboard class. Yet she is compact and sporty enough to give all the sailboard thrills without getting her crew so wet. The cockpit contributes greatly to crew comfort, allowing some place to put one’s legs and personal belongings. There is space under the decks to accommodate some limited equipment, if so desired, in addition to styrofoam flotation blocks. There are three simple rigs shown for this craft and there is also an option regarding choice of center or dagger board. The masthead or marconi rig is probably the best for those seeking speed while the lateen or gunter rigs are more suitable to portability and general handling. Sail area is modest, with an eye toward the novice sailor.

Rinky Dink-A 12 Ft Stitch & Tape Day Sailer (Pub. No. 5280)

by Pete Smyth

Sew this plywood hull together—then fiberglass it. Easiest yet!

To build the Rinky Dink you’ll need the following: 2 sheets exterior type plywood ¼” thick by 4’ x 12’; 1 sheet exterior type plywood ½” thick by 4’ x 8’; 10 yards of 44-inch fiberglass cloth, 10 ounce; 4 five-yard lengths of fiberglass mat, 2 ounce. Sufficient resin for the above. Basically, the boat consists of two sides; two bottoms and two transoms bonded together with fiberglass mat, tape and cloth. Rigitity is supplied by the seats and the
centerboard trunk.

Famous San Francisco Pelican, The (Pub. No. 5282)

by William H. Short

This champion “little ship” is easy to build, sail, handle, own and love.

The Annual San Francisco Trans-Bay Pelican Race has already become a popular classic. On June 11, 1966, the big event attracted Pelicans from all over California and Washington, and forty-two Pelicans participated. The race to San Francisco from Sausalito and return now includes a windward leg to test the Pelican’s tacking ability. She is smart to windward, too. Not a single Pelican capsized or met any trouble this year, although the afternoon breezes were fresh as ever. Throughout the planning research for the Pelican, the designer kept firmly in mind the challenge of San Francisco Bay’s strong winds and rough water. At the same time he was aiming at a design simple to handle-—and fast. The Pelican is a little craft capable of safely crossing San Francisco Bay’s main ship channel west of Alcatraz (the weather side)from Marin to San Francisco in the strong afternoon winds. On the face of it, none of this seems impressive, until the size and type of boat is known—-a stalwart 12-ft. centerboarder! Briefly, her great stability and buoyancy are created by combining the lines of the famous Banks fishing dory with the Oriental sampan. Foredecks, side decks and ample stern deck, make her exceptionally dry. Real coamings around the entire cockpit

Horizon--A 24 Ft Family Auxiliary (Pub. No. 5283)

by Peter J. Statile, N.A.

This sleek 24 Ft. family auxiliary is perfect for weekend cruises.

The ability to cruise in comfort does not require either a fat purse or a large yacht. A little ability with hand tools and some perseverance is all that’s needed to acquire this compact auxiliary with stay-aboard room and all the facilities one needs for weekend relaxation. She is a real husky little craft and will be able to take you anywhere with security. The cockpit is roomy enough for day sailing yet the galley is adequate for weekend cruising. The uniquely shaped cabin provides extra surface area for ports which produce a bright, sunny interior.

Gemini Cat--A 14 Ft Fiberglass Catamaran (Pub. No. 5284)

by S.T. Vetrosky

Here's a catamaran you can build by making a female plaster mold and forming hulls with fiberglass and polyester resin.

The hulls for this 14-foot fiberglass detachable catamaran sailboat are made by laying up 3 layers of fiberglass impregnated with polyester resin in a female plaster mold. The fiberglass hulls are approximately 1/8” thick at their sides and somewhat thicker at bottom due to resin sag. The hull decks are made of exterior plywood, coated with polyester resin on both sides. Epoxy resin is used to fasten decks to hulls. The wings are made of plywood and solid fir, screwed and cemented together with epoxy resin. Rudders are of stainless steel sheaths and aluminum blades. Stainless steel springs can be added to hold retracted rudders in raised position. Gemini Cat can be disassembled by removing sixteen 1/4“ bolts which attach hulls to wings. This feature enables one to completely build the boat in a basement, remove the finished parts and assemble outdoors. Also, the boat, when disassembled, can be car topped for transport.

Dolphin--A 21 Ft Motor Sailer (Pub. No. 5285)

by David ft Beach, N. A

Here’s a neat 21-foot sea-going outboard powered motor-sailer.

The specific purposes for which "Dolphin" was designed will appeal to many small cruiser enthusiasts who are not attracted to the high speed boat which forces them to schedule their trips by the location of fuel pumps. Of course, she will also appeal to the cruising couple who will want to tilt up the engines and sail when the wind is right. These people will admit, however, that although "Dolphin" is a motor-sailer, she is more power boat than sailing machine, and this fact should be recognized by all concerned from the very beginning.

Manu--A 30 mph Planing Sailboat (Pub. No. 5300)

by William D. Jackson, Naval Architect

Have you ever sailed in a planing-type sailboat? If you haven’t you have a real thrill awaiting you. The difference between sailing a planing-type sailboat and the conventional displacement-type sailboat is about the same as chugging along in an outboard powered, displacement-type row boat as compared to breezing along in an outboard planing-type runabout. It’s a remarkable experience to actually feel the hull of a planing sailboat rise and go skimming across the surface of the water at 18 to 30 mph! That’s faster than the American Cup Defenders will do, which, of course, are long sleek displacement-type sailboats. "Manu’s" tremendous speed is due to (1) a new concept in design and construction of hull and sails and (2) a vastly different theory and technique of sailing than that used for sailing displacement sailboats.

Cyclone, A Hand 36 foot Auxiliary (Pub. No. 5303)

Designed by Wm. H, Hand, Jr.

After publishing information for a variety of motor boats, small, medium, and large, we depart from Custom and present this month plans, specifications and full details for a regular he-boat. A full-fledged deep water craft less than 40 feet long, but oh—what room there is to be had in a boat like this. Mr. Hand has outdone himself this time. Cabins, quarters and all accommodations are large and commodious, There is ample deck space. Cockpit is wonderful and altogether there is room to spare at all points. This capable little boat takes the form of a sloop and is just about 30 feet long on the waterline. The overhang forward and aft increases this length to 38 feet 61/2 inches. All old sailormen will delight in seeing a sloop yacht of this kind; The typical Hand sheerline lends a grace and distinctiveness to these down east fishing type schooners, which is a feature in itself. Along the New England Coast fishing is the business of many industrious natives. The vagaries of the weather are not permitted to interfere at all with their comings and goings. Their boats are used at all times, both winter and summer, in storm and calm. They take the weath,er as it comes, the good with the bad. As Mr. Hand says in talking of this sloop, it can go anywhere the water is deep enough, cross the ocean if necessary, if you are a real sailor and navigator. Much more substantiaHy and heavily built than is customary in motor boat construction, boats of this kind are endowed with a remarkably long life. Witness, for example, some of the early Hudson River sloops which were built before the days of the steamboats The last few of these are just about disappearing after a long strenuous life. Since the sizes of timbers and frames in Cyclone are very heavy and substantial it is questionable if there are any amateur builders in the country with either the ability or plant, facilities sufficient to undertake single-handed a boat of these pretentions. The information given is complete and to the point. The outboard profile also gives the sail plan. Construction sections and plans will show all sizes of materials and fastenings entering into the boat.

Read What Mr. Hand Says About Cyclone
A Plea for the Auxiliary

Those who love the sea and real cruising on blue water, who like the feeling of a seaworthy, substantial, and able sailing craft which is really “bigger than the weather” in the summer months, will do well to seriously consider the type represented by this little sloop. She is a boat in which you may cruise in safety and comfort anywhere the water is deep enough,—yes, across the ocean if you are a real sailor and navigator. No motor ever built will equal the smooth, quiet, and even driving power of a good breeze, and the sensation of bowling along with started sheets cannot be equalled on the water, under the water, or in the air. The throb, roar, rattle, and vibration of man made machinery may be exhilarating, but it is also nerve racking, and cannot be favorably compared with the soft, smooth driving power of God given wind. Yes, of course, the wind fails at times and sometimes one is in a hurry, then you may start your motor and slip along at good speed with far less noise and vibration than in a comparatively lightly built “express cruiser” or standard “cruiser” of motor type.    This little sloop is really a little ship,—a sailor’s boat, and her lines, construction and details follow the very best practice of the modern fisherman type for deep water work. Below decks she has a real cabin with all cruising conveniences for a party of four. She is not a floating bungalow, but a snug and trim little cruiser in which you may really cruise.    WILLIAM H. HAND, JR.

Tangierman--A 32-Ft. Skipjack (Pub. No. 5308)

by J. A. Emmett

Tangier Man is no new type but a true Bay skipjack. Her hull lines are exactly those of the larger dredge boats which work all winter long down on the Chesapeake, in weather good and bad, dredging oysters under sail, power not being permitted for this work. Aside from the true sharpies this deadrise type with its cross-planked bottom is perhaps the cheapest and easiest kind of boat for its size not only to build but to maintain. Low cost materials can be used in her construction but to have her look well care must be taken with the building: she will be shippy looking and in keeping with her type if joints are carefully fitted and fastenings correctly driven. She is not a small boat by any means, and heavier than ordinary materials are used in her construction, but this has been laid out with home building in mind. She is a little large to be tackled as one's first attempt at boat building but is an excellent proposition for the man who wants something larger than his present craft and who has some idea of boat building procedure. If he has previously constructed one or two small boats, so much the better. And best of all is the fact that most of her fittings and gear can be homemade, making her completed cost perhaps half that of a yacht-type boat her size. Skipjack hulls are very shoal draft—Tangier Man draws only 2½' with her board up—and they are low-sided. This limits headroom in the cabin to 4', but aside from this there is exceptional accommodation aboard with more than usual deck and cockpit space. This headroom is not so bad—anything between this and enough to really stand erect is apt to be a nuisance in that you're as likely to bump your head with 5 foot headroom as with 4. As it is, there is good sitting-up space over the settee and berths and the large companionway hatch will be appreciated by the cook. The bridge deck and cockpit give ample room for outdoor living—and that's where a crew spends most of its time aboard, especially in warm weather, whether it's sailing or merely lounging. Do not attempt to gain more headroom by raising the sides of the hull or house—too many deadrise boats have already been spoiled both as to appearance and sailing qualities by doing this.

Broadbill--A 33-Ft., 9-Ton Tancook Schooner (Pub. No. 5310)

by I. A. Emmett

Nova Scotia's harbors, as you'll know if you've ever been there, are chock full of as lovely schooners as any sailing man might wish to see. Able boats all of them, and invariably slim and fast to get about under sail alone. Shelburne and Lunenburg builders turn out the larger boats for Banks fishing but Tancook Island in beautiful Mahone Bay is the home of the little Tancookers; schooner-rigged boats from 25 to 50 feet, some with the usual transom stern, others double-enders. Broadbill is the latter type modified slightly to put power aboard but otherwise as fast and able as the Island boats. She is designed for easy and low cost construction within, of course, the limits of the round bilge type and the room aboard. While construction is on the heavy side, the main members are reasonably small, the keel comparatively short and straight with no edge shaping required, and all ballast with the exception of the grounding shoe of stock bar iron is carried fisherman fashion inside.

How to Build Frisky--A 17-Ft. Racing Sloop (Pub. No. 5314)

by J. Julius Fanta

A 17-foot jib-headed racer that meets the popular demand for a racing craft combined with a knockabout for 1eisure1y afternoon sailing.

Frisky is specially designed to fill a double bill embodying a fast hull, 'with sweeping lines and novel features. She has a shallow forefoot, a factor that makes her fast, particularly in running before the wind. With the crew's weight shifted aft to lift the bow, the effect is virtually planing. The graceful sheer adds to the freeboard forward to make for dry sailing. Ample beam, six foot plus, makes this craft stiff in strongish winds. Frisky is a good sail carrier in heavy going with her tall rig.

Picaroon II--A 20-Ft. Auxiliary Cruiser (Pub. No. 5316)

by S. S. Rabl

Many will recall the boat Pixie. Pixie proved very popular indeed, and more than a few of her are riding at anchor at this moment or sitting on cradles for the winter, depending on their latitude—boats that were built by readers of the previous edition who decided Pixie's design nicely filled their requirements. As a result of numerous requests from other readers, a modified version of this boat with various improvements has been designed and is presented herewith. The new craft, named Picaroon II, has the same basic profile as Pixie and some of the parts, such as the rudder and keel casting are identical. Her hull, however, is of quite different construction and bears little sectional resemblance to her forerunner's. Picaroon's plans literally show two separate boats, one having a round bottom hull, and the other a Harborform or multiple chine hull. The round bottom version must, of course, be planked up in the regular manner, while the Harborform is constructed of marine plywood. The actual result of this multiple chine construction is the achieving of a craft with all the desirable qualities of a round bottom boat, yet having the building simplicity of the vee bottom type (which the original Pixie was) coupled with the advantages of marine plywood.

Polar Bear--A Ten-Metre Ice Yacht (Pub. No. 5320)

Organized ice yacht racing is increasing rapidly. As with sailing yachts, successful competition in racing depends largely on restricted classes or one design boats. And what a thrill there is in racing at a mile-a-minute! The Polar Bear was developed for class racing at the Maumee Bay Ice Yacht Clubs, Toledo, Ohio, and has proved to be a very popular and successful boat. In general appearance it is somewhat similar to the larger and more expensive 15 metre class, and these speedy little boats will doubtless be widely adopted elsewhere for class racing.
